The current guidelines are as follows.
Spanish authorities require everyone entering the country to be either recently tested, recovered from Covid, or fully vaccinated. This protocol is controlled at the Spanish border.
IOTSWC expects its exhibitors and attendees to also be tested, recovered, or fully vaccinated. In common with practice at other Spanish and European venues we will not ask for documented proof.
There is no longer a requirement to wear face masks in Spain, except in certain settings such as on public transport. Within the Fira Gran Via there is no requirement for mask wearing or social distancing, although you may wear a mask if you wish to.
Knowing your Covid status is important not only for yourself, but also for those around you. Self-testing is a risk-reduction measure that protects you and others. Testing is critically important, regardless of your vaccination status.
